Applicationfiled January 28, 1315. Sci'ia1No.4-,895.

To all whom it may concern Be it known that we, imon Coss and WILLIAM STooxHiLL, citizens of the United States, residing at Glassport, inthe county of Allegheny and State of Pennsylvania, have invented certain new and useful Tmprovements in Door-Hangers, of which the following is a specification.

This invention relates to improvements in hangers for freight car doors and pertains more particularly to that type of hangers for doors wherein the car entrance is sealed against the entrance of unauthorized persons and the weather.

The principal object of our invention resides in the provision of improvements in hanger for freight car doors wherein the binding of the door is obviated and which has no complicated parts to get out of order.

Another object of our invention is to provide a hanger which e'venly balances the door so that the same may be operated with the least resistance, overcoming the tendency to bind so common to car doors of other constructions, and which is simple, durable, economical of construction and efficient in operation, and it consists of the features, combinations and details of construction hereinafter described and claimed.

These together with such other objects as may hereinafter appear or are incident to our invention, we attain by means of the construction illustrated in the preferred form.

In the accompanying drawing Figure 1 is an elevation of the outside of a box car embodying our improvements, with the door in closed position. Fig. 2 is an enlarged detail view of a door hanger and roller with portions of the former broken away. Fig. 3 is an end elevation of the hanger with the suspension rail or track in section. Fig. 1 is an enlarged elevation of a modified form of door hanger.

It is obvious that in the well known construction of car doors the natural tendency of the door is to bend, due to climatic conditions or from complicated parts, such doors have many disadvantages incident to their use and in the main part the difiiculty encountered is in operating the door and establishing a perfect union of the car body and the door, providing to some degree against the entrance of water and foreign matter between the body and the door.

Our improved hanger is primarily designed to overcome the tendency of the door to bind and with that in view we have equally balanced the door at its corners on the rails, so that the operation of same is accomplished with the least resistance.

In carrying out our invention we show a freight car provided with an outside door 5, arranged to cover the entire door entrance and slidably supported at the top and base and on rails '5 and 7, preferably of round shape.

Rails 6 and 7 respectively the upper and lower supporting means are detachably mounted in the standards 8 and are formed at one end with enlarged portions or heads 9 and screw threaded portions 10 at the opposite ends, the former serving to limit the movement of the rail in one direction, while the latter carries the nuts 11 which serve to hold the rails in position.

in the preferred form the hangers comprise metallic bands 12 which are screwed, or appropriately secured to the side edges of the door extending the entire length thereof. The bands 12, adjacent the opposite ends are punched to form the slots 13, and the metal at this point is bent over to form bearings for the rollers 14, which engage the top of rod 6 and the bottom of rod 7 respectively. The rollers 14 have extensions or hubs 1 1 which normally seat in the apex of the bent over portions of the bands 12 and support the door on the rails.

By supporting the door at each corner it is obvious that the weight will be equally distributed and any force to actuate the door will be likewise distributed, preventing the binding of the door at any point. i

The modification illustrated in Fig. 4 discloses an integral hanger member adapted to be secured to the corners of the door and having an outwardly flaring body portion 15 which is apertured at 16 for the reception of screws by which it is secured to the front side of the door. The body portion 15 is bent at right angles to form the edge portion 17 and an extension 18, forming a continuation of the edge portion 17, is punched adjacent its upper end and bent over to form a bearing for the roller 19 which seats in the apex of the bent over portions of extension 18.

Rods 6, 7 are provided with stops 20, which limit the travel of the doors in both directions.

The door is adapted to move easily on the rods, the rollers being provided with half.

circular grooves 21, which engage the upper and lower circular periphery of the rods 6, and 7, reducing the friction to a minimum, and thereby eliminating any tendency of the door to stick or bind when pressure is applied thereto.

It is obvious that a door suspended in the manner set forth wherein the weight is equally distributed, will overcome the te11dency to stick or bind and will at the same time require less exertion or pressure to move it.

We do not restrict ourselves to the exact embodiment as shown, as it is obvious that certain structural variations 'may be made which come Within the scope of the'claims herewith appended.

Having thus described our invention and illustrated its use, what we claim as new and desire to obtain by Letters Patent is the following:

1. The combination with a car or the like structure having an opening and a door for closing said opening, of hangers secured to said door and formed of metal slotted adjacent their ends, said hangers at this point being bent over in substantially U shape, rails arranged on said car in proximity to said door opening, rollers carried by said hangers and formed with extensions, said extensions adapted for engagement with the said hangers at the apex of the bent over portions of said hangers for supporting said door on said rails.

2. In a hanger for sliding doors for box cars or the like, having supporting rails, comprising metallic bands secured to the side edges of door, saidbands adjacent their ends, being slotted and the band at this point bent over in substantially- U shape, rollers carried by said bands and having extensions adapted'to seat in the apex of the bent over portions of said bands, said rollers engaging the said. rails for supporting said doors thereon;

In testimony whereof we affix" our signas tures in presence of two witnesses.
